21 Claims. (Cl. 66-89) This invention relates to improvements instraight knitting machines for knitting fashioned stocking or otherblanks and more particularly to mechanism for universally controllingthe fashioning mechanism of such machines.

In straight knitting machines of the type for knitting fashioned fabricblanks such as stockings, the selvage edges of the blanks are fashionedby varying the endwise movement of the yarn carrier rods and thenarrowing point combs. The endwise movement of the carrier rods iscontrolled by end stop devices-carried on threaded spindles and thepoint combs are moved by nuts also carried on threaded spindles. ineither directionto vary the position of the stop devices and comboperating nuts by pawl and ratchet devices.

In the usual practise, the spindles for the carrier rod stop' devicesare moved in either direction in two needle steps and the spindles foroperating the point comb nuts are moved in the narrowing direction inone or two needle steps and in the widening direction in one needlesteps. Also, the point comb nuts are moved idly in the wideningdirection in one needle steps. The sequence of operations of the pointcomb nuts and particularly the idle movements of the nuts is frequentlyvaried to produce different fashioning mark effects along the edges ofthe fabrics. fashioning'operations is controlled by selecting means,which in turn is in part controlled by the movement of the end stopdevices and in part by the pattern chain devices of the machine. eachvariation in the sequence of steps to fashion the selvage edges of theblank usually requires extensive changes in the selecting means inaddition to a rearrangement of certain of the control buttons on thepattern chain resulting in a considerable loss in time and pro-.

duction.

Also, during the fashioning of the various parts of the blanks, thecombs must be repositioned to vary the number of points in thefashioning process. To so vary the position of the point combs, thespindles must be manually rotated, which action is performed severaltimes during the production of each set of blanks and at the completionof a set of blanks, the spindles must be similarly manually rotated toreturn the carrier rod end stops and the narrowing point combs tostarting position for the start of the next set of blanks.

It is an object of the present invention to provide novel means in astraight knitting machine which permits a variation in the fashioningsequence without changing the operating and controlling parts and with aminimum of time spent in adjustments of themachine.

Another object of the invention is' to provide means to automaticallyreset the point combs of a full-fashioned knitting machine for knittingstocking or other fabric blanks to vary the number of narrowing pointsin the fashioning operation in the different portions of the blanks.

A further object of the invention is to provide means The spindles arerotated.

The movement of the spindles for the various However, in the knownmachines 2,374,557 Patented. Feb. 24,-1Q59 in a full-fashioned knittingmachine for automatically controlling the operation of the narrowingmechanism to fashion stocking fabric blanks, to reset the narrowingmechanism to perform the different fashioning operations, and to returnthe narrowing mechanism to starting position at the completion of thefabric.

With these and other objects in view which will become apparent-from thefollowing description and the accompanying drawings, the inventionresides in the novel elements, features of construction and arrangementof parts in cooperative relationship as hereinafter more particularlypointed out in'the claims.
